  This update helps to recognize compatible cartridges or continuous system with self-resetting chip that I stopped recognizing due to firmware update in Epson WF-7510 Printer.

  Absolute lifesaver. Saved me about $100 and 2 hours driving.

  Nevermind. Did more research and to resolve the error, aside the firmware downgrade, I removed the ink, unplugged the printer, turned the printer back on, and placed the Ink's in individually pressing done after each ink. Doing this I was able to get it back up and running again. Thanks!

  I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer. (Epson WF-3720)
